Its not even about deserving it. How are going to maintain a terraforming project or build habitable orbital platforms if we can't manage keeping our natural habitat habitable?

Maybe projects like this would distract us from stupid tribalism ?

distractions don't solve problems. "just do the projects" doesn't resolve the management issue anyway. the climate crisis is a result of our inability to coordinate mass actions on a planetary scale to avoid damaging our habitat.

Maybe it would profoundly exacerbate preexisting inequality under the guise of betterment for "all" mankind.

Someone gets to choose who lives on these outposts.

Maybe if we worked together, we could actually use robots to do a lot of the initital work, then head over for fun when it's getting nice?

Once can dream I guess...
